This is usually addressed by installing a python3-dev package, or
similar. What did you do?

The all caps `PYTHON3.6M` and `/ETC/ALTERNATIVES/LD: CANNOT FIND
-LPYTHON3.6M` seem pretty weird to me.
It might be helpful to share a full transcript (prompts, commands,
output) of the installation (including creating a virtualenv or venv,
etc)
